Hey guys, I'm working on a program for viewing PDF files in Java and I need a system to upload essays in to an SQL database to be pulled by the Java.
I know some basic java but 0 php. A friend has helped me with this basic code and now it is 90% there I just need 1 change.
Right now the dropdown to select which essay(pdf file) submission has no effect. I would like it so that if you choose 'Deadline 1' it uploads the essay into the field "essay" if you choose 'Deadline 2' it uploads into essay2 and etc. Also it would be great if it would not allow the user to upload the essay if the field already contained any data. Thanks for any help.
Here is the code.
